Will the stock fuel pump with 47lbs injectors be able to keep up with the fuel needs using the 74mm pulley with a stage2 r push charger and long tube headers or will I need to upgrade the pump/ buy a boost-a-pump

JasonS

Do you need to upgrade your injectors to run the 74mm pulley. I'm using a Roush stage 3 on my gt.

Derek21

injectors are not typically required with the C&L Supercharger Pulley, but this will depend on your current injector size as well as all other mods done to the car that will effect the final horsepower output.

My mustang is my first car and every time I look at it, I remember how lucky I am. Ever since I saw a grabber blue GT500, I knew I had to have a grabber blue car. I've done a few modifications to the car since I've gotten it, and of course there's many more to come.
